RAIN SIGNAL.

'Applicationfiled July 2, 1920.. Serial 1511393301.

To all whom it may concern:

Be it known that ANTON A. LIBERA, a citizen of the United States ofAmerica, residing at Thorndike, in the county offlampden and State ofMassachusetts, has invented certain new and useful Improvements in RainSignals, of whichthe following is a specification.

This invention relates to improvements in rain signals and its leadingobject is to pro-,

vide a rain signal including an audible alarm and a breakable stripnormally retained'under tension to hold the alarm inoperative andadapted to beweakened by the deposit'of rain thereon, to permit of theoperation of the alarm at the time of the fall of the rain.

Another object of the invention is to provide'improved means for holdingthebreak able strip under tension and means co-operating-therewith torelease the alarm mecha- Another object oft-he invention is to provide asupport capable of adjustably hold-- ing the devicein various angularand spaced relations to a window sill. lVith the above and other objectsin view the invention relatesto new. and useful improvements,combinations, and arrangement of parts clearly described in thefollowing specification and fully illustrated in theaccompanyingdrawings, in which:

Figure 1 is a side elevation.

Figure 2 is an end view.

Figure 3 is a top plan view.

Figure 4 is a' longitudinal sectional View. Figure 5"is a detailed viewshowing the automatic trip for releasing the signal retaining lever. v i

Referring to the accompanying drawings 5 designates a case comprising ahousing 6 for the signal and the actuating mechanism therefor and ahousing 7 adapted to contain a roll of breakable paper orthe like andmeans for limiting the unrolling of the paper whereby the paper can bemaintained under tension, the housing 6 being connected to the housing 7by means of downwardly offset bridge piece or connection 8.

In the housing 7 a supply roll 9 is mounted upon a shaft 10 which isjournalled on the sides of the case 5 and carries on one end a crank 11.The roll 9 is engaged by a brake shoe or the like 12 which is carried bythe arms 13 and 14 pivotally mounted upon the shaft 15 journal led onthe sides of the housing 7. The shoe 12 is held under tension againstthejroll- 9 by means of a spring-1 6.5 i

mounted upon the-shaft 15- and arranged to maintain tension against thearms13 and. 14; The shoe 12 is disengaged from the roll,

9 by means of a lever 17 pivotally connected at 18 to said shoe andprovided with a pin 19 having sliding connection in a slot'20 of the arm2l fiXed ing 7. s 1

to the shelf 22 of the hous- The web or strip 23 from'the roll 9 is e xtend'edacross-the connecting or bridge piece 8 andis,grippedbetweenthelower jaw 24' and the upper j aw 25 of a clamp carried by the springpropel-led slide26. The upper j aw. 25 is mounted upon the side bars 27pivotally supported by the-shaft 28 carriedthe slidingbase 26. Theshaft-28 carries a spiral spr1ng wh1ch.ma1nta1ns tension against' alever 29 having connection atone-end with the upper jaw 25 and a fulcrumuponthebar; 7 30 connected with the side bars'27'. By de. pressing theterminal 29? the upper jaw'25 .may be elevated above the lower the web23 secured there between. I v The base 26 is mounted to slide on' horijaw: 24; and

zontal guides 31 provided on opposite sides of i the housing 6 and ispropelled by means of a spring 32 which is secured at'oneend at 33 andat the other end engaging alever-34 which is pivoted at 35 to the.housing"6. and is pivotally connected with .thelink 36 which link ispivotally connected with the upright lever 37% 38 and the'leverf37ispivotally connected at 39 with a'lug '40 provided'onthe under side ofthe sliding base 26.

In thehousing 6 a clock spring mechanism of any suitable type isarranged, the main shaft' 41 OfvWlliCh extendsthrough'thesides oftheihousingand is adapted-to carry the winding key '42. The clock springmechanism is adapted to operate a'Vibrating.ham-.

mer 43 which is adapted to strikeagainst the bells or gongs or audiblesounding means 44' supported upon the upright posts 45 carried by theshelf 46 arranged within the housing 6. The mechanism by which a hammer43 is vibrated may be-of any desired type, such as that as is used inalarm clock constructions.

The vibrating hammer 43 is mounted upon a shaft which is equipped withthe usual stop arm and this stop. arm is adapted to be engaged by a pin48 carried by alever 49 pivotally supported upon the shaft 50 whichshaft is supported at its ends on the housing 6 An abutment plate 51 isconnectedto the lower end of the lever 49 and a lever 52 is pivotallyconnected at 53 with the lower end of the lever 49 and extends upwardlyand has connection at 54 with the lever 55 which is pivoted at 56 to theshelf 45 by means of a lug or the like 57 carried by said shelf.

The lever 55 carries a weight 58 on one endthereof and is provided witha slot 59 in which the upper end of the lever 49 works I the fall ofrain water thereon and said web breaks under the tension maintained bythe spring 32 the arm 62 will strike against theabutment plate 51 andthe lever 49 will be moved away from the stop arm 47 so as to disengagethe stop pin 48 from said arm 47 and the hammer 43 will be released tovibrate. under the automatic action of the alarm spring mechanismcontained in the housing 6. When it is desired to lock the hammer 43against movement the shaft 63 which'carries the crank arm 64 may berotated so that the crank arm 64 will engage the hammer 43 and preventvibratory move ment thereof.

It will be seen that when the-web 23 is maintained under tension by thepropelling spring 32 and said paper web or the like is weakened by rainwater so that the tension of the spring 32 will break said web thestriker arm 62 will be propelled by the action of the spring 32 so as toabut against the plate 51 and disengage the stop pin 48 fromthe arm 47so that the hammer will be released to vibrate under the actionof thespring mechanism until manually stopped by operating the shaft 63 bymeans of its crank 63 The mechanism contained in the housing 6 isprotected by means of a swinging cover 65 and the mechanism contained inthe housing 7 isprotected by aswinging cover 66. r

The case 5 is provided with depending brackets 67 which are pivotallysecured to the upstanding brackets 68 carried by the vframe 69. Theframe 69 comprises parallel spaced plates each of which is formed with aslot 70, the two slots being disposed in alignment. Between. the plates69 the head 71 of a clamp member 72 is adapted to slide,

said head being formed with outwardly proj ecting lugs 73 which slidablyextend through the slot 70. The clamp member 72 carries a clamping screw74 which is adapted to engage the shank 75 of the clamp member 76, whichis equipped with a screw 77. The device is clamped between the head 77of the bracketscrew 77 and the jaw of the member 74, as shown inFigure 1. this relation the frame69 maybe slidably shifted upon the lugs73 or'the case 6 ad j usted to various angular relations by reason ofthe pivotal connection between the bracket 67 and 68. This angular adjustment may be varied at will by means of the screws 78 and 79 which arepivotally secured at their ends to the brackets 80 and 81 carried by thecase 5 and the frame 69'respectively. The confronting ends of the screws78 and 79 are provided with right and left screw threads and are engagedby the turnbuckle'82, the manipulation of which will adjust the case 5at various angular relations upon the brackets 67 and 68.

- Having described myinvention I claim 1. A rain signal'comprising acase having a'roll therein, an absorbent rupturable strip on the rollerand extendable therefrom, means :for retarding the rotation of the roll,means for holdingsaid strip under tension slidable on said case, and asignal adapted to be actuated by said means onthe rupture of said strip.i i

2. A rain signal comprising a case, an audible signal therein, a memberslidable on the case and having means to actuate the signal, said memberbeing provided with a gripper means for holding said member undertension, a fabric strip adapted to be clamped by said gripper, a rollfor said strip, and a tension device for said roll, said case beingprovided witha gap across the said a strip to receive rain drops. 1
